A gene is a basic unit of heredity in a living organism that normally resides in long strands of DNA called chromosomes. Genes are coded instructions that decide what the organism is like, how it behaves in its environment and how it survives.
Best Answer: DNA is the entire genetic material. A Chromosome is a strand of DNA containging the genes. A gene is a part of a chromosome which carries the information that is passed on to offspring.ll such genes are packed in cells in the form of chromosomes. Such closed parallelism was recognized by Sutton and Boveri between genes and chromo somes. PARALLELISM BETWEEN GENES AND CHROMOSOMES The chromosomes, and therefore the genes, are made up of the chemical substance called DNA.
